This 'intention relatesto shoe sole "trinimers, one of the objects being V)reduce a device whereby marginal portions of soles can be easily, quiclrlv and accurately trimmed to the desired contour.

Prior to this invention, the heel po of shoe soles have been generally car Yui'iy trimmed by hand, and even though skilled operators are c-unployed,V the work is beth difficult and expensive. j My object is to ininimize the labor and expense, and also io perform this work with a high degree o3; accuracy not obtainable from the hand operations.

@Wing to the irregular lcontinu' of a shoe sole, the problem of devising a machine to accurately trim the heel portion involves the diiculty of properly positioning the sole to receive the cutting edge, and l have shown how the desired result can be accomplished by using a gage to locate the toe portion in a predetermined position relative to the Y ib edge. More specifically stated, the invention includes a trimming element hay-V ing a cutting edge conforming to the contour desired at the heel portionr of a sole, and a gage contacting with the irregular sole to properly position it witliL respect `to the cutting edge. A. further object is to provide a device of this kind adapted to receive both right and left soles.-

Another object of the invention is to produce an adjustable device to receive soles of different lengths and shapes, and I have also provided indicating elements to show the size and style for which the machine is adjusted. n

A further object is to produce a. device adapted to trim the heel portion of a sole having a long tongue to cover thebreast of a shoe heel, the tongue being displaced during the trimming operation, so as to lie entirely beyond the cutting edge. After the heel portions have been trimmed by this ma*- y chine, they may be skived by anotherl ma-l chine or in any other suitable manner.

Nith the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention.V However, it is to be understood that the invention comprehends changes, variations .and modifications .A CRRATN OF MISSOUR.

Fig. 9 ,is a top view of the parts shown in Fig. 8." j

To illustrate one form of the invention' l have shown a table l supported on a member 21 (Fig.` l) slidably mounted inV a vertical guide ,3 and having a threaded lower end 4 whichcooperates with a nut 5 to permit vertical adjustment of the table. The adjustable supporting member 2 is provided with a pin 6 extending into a slot 7 to prevent rotation of the table.

Figures 2, 8 and 9 show the manner in which a sole D can be positioned between a toe gage E and `a heel gage F to receive a cutting yelement G having an approximately ll-shaped cutting edge adapted to contact with the heel portion 'of the sole as indicated by the dot and dash line G in Fig. 2, so .as to remove the marginal portion outn side of said line. l

The toe gage E is mounted on a plate 8 slidably fitted to a guide 9 on the table l, said guidehaving side members l0 (Fig. 5) with beveled inner faces to receive the correspondingly beveled side edges of tbe plate 81. The plate 8 can be adjusted in the guide 9 to move the toe gage E toward and away from the heel gage F, and after 'the desired adjustment has'bcen made, the plate 8 can be secured by means of a locking bar 11 (Figures 2 and 3) beveled at one end to engage the plate 8 and having a downturned extension 12 at the other end which rests upon the table 1. This table is threaded to receive a screw 13 (Fig. 3) which passes through the locking bar 11 and has a head 1/1 contacting with the top of the bar t force the beveled end of said bar onto on of the beveled side edges of the plate The guide 9 is recessed at 15 (Fig. 2) to ro cei've the locking bar 11.

The means for shifting the slidable plate 8 to adjust the toe gage E comprises an operating handle 16 pivoted at 17 (Figures 2 and 3) and provided with an arm 18 having a slot 19 to receive a screw 20` carried by the plate 8, as shown most clearly in Fig. The screw 20 is connected to the slidable plate 8 through the medium of a t-ube 21 which is threaded to receive the screw 2O as well as a screw 22 whereby said tube is attached to the plate 8. rlhe table 1 and the guide 9 are slotted as shown at 28 and 24 in Figures 2 and 4 te form an elongated passageway for the tube 21.

The heel gage F comprises diverging abutments 25 to receive the heel portion of the sole as shown in Figures 2 and 9, and these abutments extend from a plate 26 slidably mounted in a guide 27 at the rear of the table 1. A spring 28 (Fig. 2), secured by a screw 29, has free end engaging a lug 30 on the plate 2G and this spring forces the heel gage toward the toe gage.' The pressure of the spring is very slight, so the operator can easily position the sole by first placing its heel portion in contact with the diverging faces of the heel gage, and then forcing the sole and heel gage rearwardly before arranging the toe portion of the sole at the toe gage E. The operator can thus quickly arrange a sole in the machine, and when so positioned it is held by the pressure of the spring 28 which forces the heel gage toward the toe gage. rlhe diverging` abutments 25 on the heel gage aid in positioning the heel portion.

The trimming element Gr comprises a die having a lil-shaped blade and the dovetail 31 above the blade (Figs. 3 and adapted to be clamped between jaws 33 at the lower end of a vertical rod 34e. ln Figures 3 and 7, a screw is shown to force these jaws toward each other. rlhe trimming element G is thus removably secured to the machine, and in actual practice it is convenient to use trimming elements of different dimensions for the purpose of trimming soles of different shapes and sizes. @ne trimming element can be easily substituted for another, and certain other devices can be adjusted as will be hereafter described to provide for the trimming of the different soles.

The means for transmitting power to the rod 311 for the purpose of forcing the trimming elementonto the sole is shown in Figure 1. This means comprises a lever 36 extending through the rod Bil, said lever being fulcrumed at 37. An eccentric 37 is secured to an operating shaft at the lower portion of the machine. and a circular strap, or band 39 surrounds this eccentric 40 designates a rod connecting the strap 39 to the lever 36, as shown in Fig. 1. A spring Ll1, surroumling` the rod 3d, engages a washer l2 at the top of the rod, and tends to hold said rod in its elevated position.

To prevent undue injury to the cutting edge at the bottom of 'the trimming element G, plate i3 is removably mounted in a holder lil below the trimming element. (Figures 2 and l.)

The means for releasing the sole from the lil-shaped trimming elementcomprises a stripper l5 pivotally mounted on a rod d6, and a spring 4'? (Fig. 2) engaging vthe stripper and tending to force its free end onto the yieldable sheet 43. @ne end of the spring i7 engages the stripper l5, and the other end is secured to the rod 46.

The plate 8 which Vcarries the toe gage E is adjustable in the. guide 9, previously pointed out, and this plate is recessed as shown at 18 in Figures 2 and l to receive a stationary member 1Q having an inclined top face which deflects the heel portion of the sole upwardly during the operation of placing this heel portion in contact with the heel F. ln other words, this inclined top face prevents the rear edge of the sole from striking the holder l-l in which the plate a3 is mounted.

lWhen the plate 8 is adjusted to move` the toe gage E toward or away from the heel gage F, motion is transmitted to a pointer (Fig-2) moved alongagraduated segment 51 to indicate the sizes oi the soles. This pointer is pivoted at and provided with an arm 53 vhaving a. slot 5d to receive a screw 55 carried by the slidable plate 8 to which the toe gage is secured. To adjust the machine for a sole of any given length 'the operating handle 16 (Fig. 2) is adjusted to shift the slidable plate 8 until the pointer 50 is located at the desired indicating point on the segment 51.

The toe gage E is also adjust-able to receive soles of different sizes and styles. Each ec ge of the toe gage (Figures 2 and 6) is provided with a pair of oppositely disposed curv d abutmcnts 5G to receive the toesI of right and left soles, and this plate also has suitable designations referring to the respective pairs of abutments. For eX* ample, the characters B 166 C are shown in Fig. 2 near one edge of the plate 'to show.

llt)

edge can Vbe presented toward the heel gage to locate any selected pair of the labutments 56 in its toe-receiving position.` To secure the toe gage in either of these four positions, bar 57 (Figures` 2,3, 4 and 5) is rigidly secured to the slidable plate 8 kby means of screws which appear in Fig. 4, and the bottom of the toe gage E is recessed as shown most clearly at 58` in Fig. G. Each of the recesses 58 is adaptedio receive the bar 57 and the toe gage can be thus interloclted with the slidable plate 8. s a further aid in the V'Work of positioning the toe gage it is provided with holes 59 (Figures 2 and 6) `to receive a pin 60 carried by the bar 57. When either of the rrelatively long edges of the a'e is in service, the pin 60 lies in the central hole 59, but when either of the shorter edges of this gage is to be used the pin 60 is located in the hole 59 nearest to the selected edge.

It Will now be understood that the toe gage is removably interlocked with the slidable plate 8, and that the gage itself can be adjusted relative to said plate, so as to receive soles of different styles and dimensions. In either case, When the gage is adjusted to the desired position, the plate 8 can be shifted to locate the pointer 50 (Fig. 2) in the position wherein it indicates the length of the sole tobe inserted into the machine.

Attention is also directed to the fact that the curved abutments 56 are designed to receive right and left soles, and the abutments of each pair are symmetrical with each other, but they are oset relatively to the heel gage F. rIhis is of course due to the fact that the soles are offset relative to the heels, and one abutment 56 offset in one direction to receive a left sole, While the other is offset in the other direction to receive a right sole.

The sole D shown by Figures 2, 8, and 9i is provided with a tongue 6l integrally united With the body of the sole and adapted to serve as a cover for the breast of the heel of the shoe. However, this'tongue is long enough to extend over the heel portion of the sole, and I desire to trim this heel portion Without cutting the tongue. With this object in view the operator While placing the sole in the machine, folds the tongue 61 backwardly as shown most clearly in Fig. 8. rIhe tongue is which separates it rfrom the course of the trimming element. In the structure I have shown, the tongue contacts With the upper end of the stripper 45 which surrounds the rod 46.
